NAT from a firewall perspective is "default deny in". As far as I can tell no one is arguing that a firewall should not support that. Now mangling the addresses and ports is not a firewall's job. Its never has been a firewall's job. That is what a NAT box does. Now sometimes a NAT and Firewall are implemented in the same hardware and people fail to make the distinction. As for doing the same as v4 in a firewall for v6, only a idiot would do that, as it will often break IPv6. There are rules, often deployed in v4, that are mostly harmless to IPv4 but will totally break IPv6.
